摘要： A cyclodextrin-modified thermoplastic porous layer material is prepared by coating the surface of a fibrous nonwoven web, open-celled foam, porous film or the like with a chemical composition including a cyclodextrin compound, and then irradiating the coated fabric to induce a chemical reaction between the cyclodextrin compound and the underlying layer material. The resulting cyclodextrin-modified layer material has durable hydrophilic properties useful in topsheets for absorbent articles, and entrapment capabilities useful in water filters, blood filters, controlled delivery articles and protective garments.

摘要： A fiber which includes a thermoplastic polymer and particles of a ferroelectric material dispersed therein. The thermoplastic polymer may be, for example, a polyolefin, such as polypropylene or polyethylene, and the ferroelectric material may be barium titanate. The ferroelectric material may be present at a level of from about 0.01 to about 50 percent by weight (from about 0.001 to about 13 percent by volume), and will have a longest dimension in a range of from about 10 nanometers to about 10 micrometers. The fiber may be exposed to an electric field. A plurality of the fibers may be employed to form a knitted or woven fabric or a nonwoven web. Also provided is a method of preparing fibers containing particles of a ferroelectric material. The method includes destructuring the ferroelectric material in the presence of a liquid and a surfactant to give destructured particles; the liquid is a solvent for the surfactant and the surfactant is adapted to stabilize the destructured particles against agglomeration. A blend of the stabilized, destructured ferroelectric material particles and a thermoplastic polymer then is formed and extruded to form fibers. The extruded fibers may be collected on a moving foraminous support to form a nonwoven web and, if desired, may be exposed to an electric field. The fiber of the present invention, especially when in the form of a nonwoven web, is especially suited as a filtration medium. For example, the nonwoven web may be adapted to remove particulate matter from a gaseous stream.

摘要： A method of separating at least one polymer from a mixture of polymers. The method includes adjusting the temperature of the mixture, either by heating or cooling, to bring the temperature to a temperature at which decombination of the polymer mixture occurs. Mechanical energy is also imparted to the mixture, before, during or after temperature adjustment. The temperature adjustment and application of mechanical energy enable at least one polymer to be separated from the other polymers in the mixture.

摘要： A method for coating the surface of a substrate composed of a hydrophobic polymer with a hydrophobic vinyl polymer. The method includes preparing a solution of the hydrophobic vinyl polymer in a polar nonaqueous solvent, such as 1-methyl-1-pyrrolidinone, in which the hydrophobic vinyl polymer is surface-active. The substrate then is treated with the solution under conditions sufficient to deposit the hydrophobic vinyl polymer on the substrate. The hydrophobic vinyl polymer may have readily hydrolyzable pendant groups which, upon hydrolysis thereof in an aqueous medium, will result in the formation of a hydrophilic vinyl polymer coating on the substrate. For example, the hydrophobic vinyl polymer may be poly(vinyl trifluoroacetate). Also provided are coated substrates, in which the substrate is a shaped article composed of a hydrophobic polymer. The shaped article may be, for example, a film, fiber, or nonwoven web.
